Sigal Zilcha-Mano is a licensed clinical psychologist and an associate professor of clinical psychology in the Department of Psychology, University of Haifa. Sigal is currently engaged in the study of mechanisms in psychotherapy and of the interplay between interpersonal factors and processes of change, especially in the treatment of depression.  She is most interested in separating the trait-like patient interpersonal characteristics (which can therefore serve in determining which type of treatment is best suited for which patient) from those patient interpersonal characteristics that change across treatment and drive change in psychotherapy. In particular, she is interested in understanding how both components contribute to the process and outcome of treatment.
